  • Inlet and discharge valve assemblies interchange for easier maintenance.
  • Lubricated Lo-Pressure Seals provide double protection against external leakage.
  • Oil bath crankcase assures optimum lubrication.
  • Close tolerance concentricity of the ceramic plunger maximizes seal life.
  • Optional Belt Drive or Motorized versions offer system flexibility.

Quality Materials:

  • Precision design 304 stainless steel valves and seats are hardened and polished for ultimate seating &
  • extended valve life.
  • Brass manifold is strong and corrosion resistant.
  • Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and
  • extended seal life.
  • Specially formulated, Hi-Pressure Seals offer unmatched performance & seal life.
  • Die cast aluminum crankcase provides high strength, minimum weight and precision tolerance control.
  • Chrome crankshaft gives unmatched strength and surface hardness.
  • Oversized crankshaft bearings with greater capacity mean longer bearing life.

Easy Maintenance:

  • Wet-end is easily serviced without entering crankcase, requiring less time and effort.
